SCREEN .IPPARATUS FOR PIVOTED SASHES.,

Application filed April 3, 1925. Serial No. 20,388.

. This invention relates to screens and screen apparatus tor pivoted orswinging sashes.

rlhe main object ot the invention is to provide simple but highly'eiticientl screen appa ratus for pivoted sashesto be used in combina.-

`tion with upper and lower screens disposed" :tor closing these openings.and thereby ex-l cluding flies and other insects. f

A further object of ,theinvention is to pro vide apparatus, including ameans rmounted adjacent the lower edge Hoft the upper sash for closing.the space betweenxthe yupper screen and the outside of they sash, and`means rigidly carried by the sashforiclosing the opening between thelower screen `and the inner side ot the sash. n t

lt is a still Vfurther object to lprovide in suchapparatus, means forclosing oit the openings which are `formed at the ends-ofsaid closingmeans when the sash is swung tocertain positions. t A,

4These and other.objects ot lthe invention will be apparent from thefollowing description made in connection with the accompany ingdrawings, whereinv like notationsV refer to similar partsvthrouglioutthe several views, and in which l y Fig. l is an elevation of the outerside ot a swingingsash mounted -in the sash frame and equipped withapparatus in accordance with this invention; y

Referring to the drawings, a standard trame for swinging sashes isillustrated, havlthe angular shoulder 14".

ing the angle bar yside Amembers 6 andi/the similarly constructedAtransverse top yand bottom lmembers, 7 secured therebetween,Weatheringmembers in the term ot' channel 'bars 8 are lsecured on theinner sidesct the side members 6 extending from points below the axis oithe sash to the `bottom of the trame, kalici-ding'k the two weatheringpoints as best seen in Fig. 4, one at either side ot the sash. .A pairotrugged oppositely alined angular brackets 9 are rigidly secured to theinner sides vot the sidemembers 6 of the trame having alined bearingsattheir outer ends disposed in the interior sidefot the frame.y-I"ransverse weather strips v7a and 7b are secured at the topk exteriorand bottom interior ot the frame, respectively7 to which the rscreenmountingistrips y10 are secured.,V f y v,

A standard'swinging sash, designated as an entirety by the letter Acomprises the side muntin boards 12the angular bottom and top limitstops,one extending onthe interior and thel other on the exterior ot the4trame,

respectively, and the .y usual glass panelQC.`

Brackets 1l aresecured at'either side of the ,p

sash yin alinement with brackets' 9` carried bythe frame vand areprovidedwith `oppof sltely allned bearings 'throughwhich and throughthebearings and brackets 9, netted bolts llffare secured, pivotallymounting the sash A in the sash frame.r y

Channeled weathering members 13 are secured ateither side of the sash Aextending from points slightly above. the axis of said sash tothe top`of the trame, `having the two weathering points adapted .to contact the'sash rframe along the exteriorlandinterior sides thereof.W y y fAbracket 14%, vhaving depending arms yat either end,'isiseou'red acrossthe outer :side of the sash `trame on av line somewhat above the axis ofthe sash, `to which is secured the strip 14 extending between the sidemuntin boards 12 of theV sash and having` -theiip standing shoulder 14bon its innen side dis-` posed in close relation to the pane k12C o'lfthe sash when the sash is closed. The `top screen 15 is mounted betweentheup'per weather strip of the sash -frame 7a and `the upper portion ofthe strip 14 andthe b0ttom edge of said screenextends directly overArcuate blocks 1G, having a radius-substantiallyequal to the distancebetween the axis ot the sash and the lower edge of the strip 14, areoppositely alined and secured to the side muntin boards 12 of the sashon the exterior of the sash and cover the space between the side muntinboards and the lower edge of the plate 14 regardless of what positionthe sash A is swung to, since the arc `of. the outer edge of said blocksis centered on the axis of said sash.

A transversely extendingl rectangular flap 17, having downturned flangesat its outer edge and end portions, extends between the side muntinboards 12 of the sash on the interior of the same and is provided withthe longitudinal channel portion 17a at its inner edge, engaging theshoulder 14h and form-V ing a hinge therewith, the .axis of which hingelies directly beneath and parallel with the bottom edge of the screen15, as shown in Figs. 2 and 5. When the sash is in closed position, asillustrated in Fig. 2, the flap 17 will be hcldbetween the screen 15 andthe pane 12C, with its axis, nevertheless, directly beneath the bottomedge of said screen and, obviously, when the sash is swung, the flapwill fall therewith, the outer flanged edge engaging the pane 12cwhereby the space be1 tween the arcuate blocks 16 and the lower edge oftop screen 15 and the pane 12c will be at all times covered by said liapregardless of the position of sash A.

The lower screen 18 is mounted on the interior side of the sash frameextending from a line slightly below the axis of the sash to the bottomof said frame, the bottom of said screen being held in the strip 10. Atransverse plate 19, having a semi-cylindrical main portion, is rigidlysecured across the interior sidev of the sash with its inner end inclose relation to the pane of said sash and having its semi-cylindricalportion centered about the axis of said sash on a radius approximatelyequal to the distance between the Y axis of sash A and the top of thelower screen 18. Obviously, since theV semi-cylindrical portion of plate19 is so centered, the space between the interior side of the pane 12cand the top of the lower screen 18 willat all times be covered when saidsash is' swung, and since the pivots of the sash are on the interiorside of the sash frame, plate 19 will be swung between the sides of thesash frame having its ends covered thereby.

In certain positions of the sash, however, the ends of the flap 17 willnot be covered by the arcuate blocks 16 and small apertures would beformed were it not for the vertically swinging depending plates 20pivoted to the outer sides of the arcuate block 16` adapted to havetheir lower edges engage the top edges of the limit stops or weatheringmembers 8. By means of these swinging plates 2O all passages at the endsof the flap 17 are closed regardless of the position of the sash.

Y From the above, the operation of the device verse plate 19 will beswung with the lower edge of its cylindrical portion engaging the topedge of the lower screen 18. The ends of the flap 17 will be covered bythe arcuate blocks 16 and the depending swing-plates 20. It will,therefore, be seen that the sash may be swung open to any positionwithout leaving apertures for flies or insects to gain entrance into theinterior of the room.

From the foregoing description, it will be apparent that simple buthighly efficient apparatus has been invented for use in connec-y tionwith pivoted sashes and screens therefor.

Extensive actual usage has proven the in" vention to be highlysuccessful for the purposes intended.

1t will, of course,.be understood that various changes may be made inthe form, details, proportions an'd arrangement of parts withoutdeparting from the scope of the invention, which, generally stated,consists in the apparatusas shown and described and defined in theappended claims.

That is claimed is:

1. In swinging sash provided with a screen, apparatus for closing thespace between said screen and said sash comprising a transverse flaphinged adjacent the lower edge of the screen and held against the paneof said sash, and a pair of narrow, spaced closure members fixed to saidsash at the ends of said flap extending in al plane normal to the paneof said sash and having an outer edge concentric with the pivot'of saidsash for closing the space between the ends of said plate and said sash.

2. In swinging sash provided with a screen, apparatus for closing thespace between said sash and said screen having in combination a rigidflap swingably j mounted from the lower edge of said screen withits freeend held against the pane of said sash by gravity, narrow closuremembers carried adjacent each longitudinal edge of said sash at rightangles to the pane of. said sash and having arcuate outer edgesconcentric with the pivot of said sash, said edges being disposedtangential to the lower edge of said screen and plates loosely pivotedto said closure members extending between the longitudinal edges of saidsash and its sash frame.

3.1n swinging sash provided with a screen,

apparatus for `closing the space between said screen and said sash,comprising an elongated plate at the lower edgefof said screen having anarrow perpendicular liange, a flap having an angle portion engagingsaid flange to permit swinging movement of said flap relatively thereto,said flap being of greater width than the distance between the pane ofsaid sash and said plate in any position of said sash, whereby gravitywill hold said flap against the pane of said sash when said sash is.opened and members at the ends of said plate extending normal to thepane o said sash for closing the space between the ends of said Hap andsaid sash.
